Abstract: A touch controller. The touch controller can include first sense circuitry configured to be coupled to a first electrode on a touch sensor panel, the first sense circuitry configured to sense a first self-capacitance associated with the first electrode, and a first mutual capacitance associated with the first electrode. In some examples, the first sense circuitry can be configured to sense the first self-capacitance and the first mutual capacitance simultaneously. In some examples, the touch controller can further include a first mixer and a second mixer coupled to the first sense circuitry, the first mixer configured to demodulate a first output from the first sense circuitry to extract information about the first self-capacitance from the first output, the second mixer configured to demodulate the first output from the first sense circuitry to extract information about the first mutual capacitance from the first output.

Abstract: An integrated Silicon-OLED display and touch sensor panel is disclosed. The integrated Silicon-OLED display and touch sensor panel can include a Silicon substrate, an array of transistors, one or more metallization layers, one or more vias, an OLED stack, color filters, touch sensors, and additional components and circuitry. Additional components and circuitry can include an electrostatic discharge device, a light shielding, a switching matrix, one or more photodiodes, a near-infrared detector and near-infrared color filters. The integrated Silicon-OLED display and touch sensor panel can be further configured for near-field imaging, optically-assisted touch, and fingerprint detection. In some examples, a plurality of touch sensors and/or display pixels can be grouped into clusters, and the clusters can be coupled to a switching matrix for dynamic change of touch and/or display granularity.
